FIELD OF TECHNOLOGY

Certain embodiments of the disclosure relate to sports performance monitoring systems and technologies. More specifically, certain embodiments of the disclosure relate to an electronic training system and method for electronic evaluation and feedback of sports performance of a user (e.g. a sportsman).

BACKGROUND

Sports have been a meaningful and an integral part of society. With greater attention on sports comes greater attention on improving sports performance of a given sportsman. Now-a-days, a person intending to prepare for a rewarding sporting career start early in life and specialize in particular areas and train year-round to improve their skills. Coaching plays a major role in improving individual and team performance that requires the coach to possess an ability to make quick decisions, supported by an intensive activity of reflection, decision and guidance to influence sporting performance. Typically, human observation and judgment are often prone to biases and it is challenging for even highly skilled coaches to measure small differences in motion and other factors of the given sportsman in a sporting event, which adversely affects next phase of training and sporting performance of the given sportsman. Currently, there exists many heath and performance monitoring systems that monitor and provide recommendations to a player. However, the monitoring and recommendations of the conventional systems are focused to a particular arena of a given sportsman and are often disconnected and not in synchronization with training methodologies of a coach of the given sportsman. Thus, a sportsman is usually in a dilemma regarding which recommendation to follow, what information to implement, and what other to ignore. The biggest challenges faced is information overload from such conventional systems, which is confusing rather than guiding to attain a desired performance. In light of the foregoing, there exists a need for a technical solution that solves the abovementioned problems and enables comprehensive electronic evaluation and convenient feedback of sports performance.

Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with some aspects of the present disclosure as set forth in the remainder of the present application with reference to the drawings.

Typically, in conventional systems, the biggest challenges faced is information overload. As a result of the information overload, a sportsman is usually in a dilemma with regards to which recommendation to follow, what information to implement, and what other to ignore, which is very confusing rather than guiding to attain a desired sports performance.

The user device 108 may be for an individual, institution, or agency that provides sports training or coaching services to a sportsman. For example, a coach, a dietician, an endurance trainer, and the like, may be considered the individual that provides the coaching or sports training. The institution or agency may be a training and coaching center, or a genetic screening laboratory or any entity that provides advisory services to users. In an implementation, the user device 108 may be associated with a coach.

Examples of the communication device 110 may include, but are not limited to a 5G-capable repeater device, an Evolved-universal terrestrial radio access-New radio Dual Connectivity (EN-DC) device, a New Radio (NR)-enabled device, or a mmWave-enabled telecommunication device. The communication device 110 may facilitate communication in both sub 30 gigahertz to above 30 gigahertz. In one example, the communication device 110 may receive/transmit the RF signals from/to a base station or from another network node.

The communication network 112 may include a medium through which the various devices in the network environment, such as the server arrangement 102, the plurality of electronic training systems 104, the user device 108, the communication device 110, and the user device 108, may communicate with each other. In some embodiments, a secured and dedicated communication channel may be established between the plurality of electronic training systems 104 and the server arrangement 102.

For example, the main AI-based system 114 may train the one or more neural network models to find a relationship between the plurality of stimuli and the plurality of responses generated in the body portions of the users 126 a, 126 b, . . . , 126 n. In accordance with an embodiment, the trained model(s) is then deployed in one or more components of each of the plurality of electronic training systems 104, for example, the local AI-based system 124. The deployed pre-trained neural network model(s) is remotely updatable as and when required. In some embodiments, the server arrangement 102 may establish a dedicated and secured link, via the communication network 112 or by use of the communication device 110 (e.g. a 5G enabled repeater device) to update various programmable components, such as the deployed pre-trained neural network model, of the plurality of electronic training systems 104. In an embodiment, the main AI-based system 114 may employ supervised or unsupervised learning model. The main AI-based system 114 may employ machine learning algorithms, such as supervised, unsupervised, semi-supervised, or reinforcement machine learning algorithms for operation thereof. Typically, the machine learning algorithms refer to a category of algorithms employed by a system that allows the system to become more accurate in predicting outcomes and/or performing tasks, without being explicitly programmed.

The control circuitry 116 comprises suitable logic, circuitry, and interfaces configured to process sensor data acquired from the set of internal response sensors 120 and the set of external response sensors 122. Examples of the control circuitry 116 include an Application-Specific Integrated Circuit (ASIC) processor, a Complex Instruction Set Computing (CISC) processor, a combination of a central processing unit (CPU) and a graphics processing unit (GPU), a microcontroller, and/or other hardware processors.

The stimulus device 118 may correspond to a human senses' stimulator device. The stimulus device 118 may comprise suitable logic, circuitry, and/or interfaces configured to applying the plurality of stimuli to the body portions of the user 126 a to increase sports performance. Examples of the plurality of stimuli may include, but are not limited to, calibrated pressure, calibrated vibration input, calibrated electric input, sound waves, magnetic input, a virtual reality or mixed reality environment output, and a combination of physical therapy and virtual reality output. The stimulus device 118 may operate under the control of the control circuitry 116. In accordance with an embodiment, the stimulus device 118 may include various stimulus sub-devices for providing different types of stimuli to different body portions of a user. In accordance with another embodiment, the stimulus device 118 may include a plurality of slots (as shown in FIG. 2 ) to detachably attach the plurality of different stimulus sub-devices 106 in the plurality of slots in a modular arrangement.

The set of internal response sensors 120 includes suitable logic, circuitry, and/or interfaces configured to sense and measure a level of an internal response generated within a body of a user. In accordance with an embodiment, the set of internal response sensors 120 may be attached to or placed on a body of a user (such as the user 126 a) in a non-invasive manner when the user is undergoing training for a sporting event or involved in actual sports activities in the sporting event. Examples of the internal responses that may be sensed and measured by the set of internal response sensors 120 may include, but are not limited to, electrical brain activity and physiological changes in a body of a user. In one example, the set of internal response sensors 120 may comprise an electromyograph for sensing and measuring activity in muscles and nerves. The set of internal response sensors 120 may further include a blood pressure monitor, a heart rate monitor, a pulse rate monitor, a temperature sensor, a low power magnetic resonance imaging system, and/or the like. The set of internal response sensors 120 may operate under the control of the control circuitry 116.

The set of external response sensors 122 includes suitable logic, circuitry, and/or interfaces configured to sense and measure an external change discernible from external surface of the body of a user. Examples of the external response that may be sensed and measured by the set of external response sensors 122 may include, but are not limited to, locomotion (i.e. movement of individual from one place to another), body movements (e.g. movement of joints, limbs, and specific sections of the body), facial expressions, skin colour, a body posture, gestures, and/or voice feedback. In one example, the set of external response sensors 122 may include an imaging device, a light detection and ranging (LiDAR) sensor, and/or a radio detection and ranging (RADAR) sensor for sensing changes in facial expressions and gestures of the user when stimulus is provided to the user. The set of external response sensors 122 may further include an audio sensor for sensing the voice feedback of the user when the stimulus is provided to the user. The set of external response sensors 122 may operate under the control of the control circuitry 116.

In operation, there may be a training phase and an operational phase of the electronic training system 104 a. In the training phase, the control circuitry 116 of the electronic training system 104 a may be configured to track movements of each body part of a plurality of body parts of the user 126 a in relation to a corresponding reference point. The tracking may occur in a plurality of sporting events from a combination of the set of external response sensors 122 and the set of internal response sensors 120. The reference point for a specific body part may be selected based on a current position of the specific body part that is tracked. In a training phase, depending on the type of a sporting event, a movement dataset from a plurality of movements dataset is retrieved and set as default to be used for reference. For example, if a golf match is played, accordingly a movement dataset prespecified for golf is retrieved. The movement dataset has collection of poor to best shots and associated motion coordinates of many test users and known video analysis from other players involved in golf play. The movements of rotate, tilt, way or manner of holding club face, posture, force applied in a stroke, etc. may be used as reference. The plurality of movements dataset may be stored in sports knowledge database (e.g. the sports knowledge database 208 or 220 in FIG. 2 ). Similarly, for a different sport, such as soccer, locomotion movements, i.e. how a player moves from one position to another position in a field where the sport is played, and the footwork may be more useful than movement of hands. Thus, more emphasis may be provided on legs than on hands tracking. Beneficially, having a specific movement dataset for a specific sport results in removal of artifacts and noise in tracking, and fine details and biomechanics may be captured with less computational processing power as a result of focused approach in tracking specific body portions more precisely.

Additionally, at the time of tracking, different reference points may be dynamically and temporally set for tracking different body parts. For example, a left hand and a right hand of the user 126 a may be tracked in relation to a hip joint in a case where the user 126 a is upright in normal standing position. However, on bending or in squat position, a reference point in ground (e.g. point of squat) may be dynamically set from tracking hand movements in an example. Torso twist (or rotate) may be tracked from a reference vertical plane (e.g. a coronal plane and a sagittal plane of human anatomy). A bend motion may be tracked from a transverse plane. Further, the control circuitry 116 may be further configured to determine relative motion of one body part from other body parts of the plurality of body parts based on the sensor data acquired form the set of external response sensors 122. Beneficially, the tracking of each body part of the plurality of body parts of the user 126 a in relation to a corresponding reference point that is automatically set as per body posture facilitates enhanced tracking and motion data capture.

In accordance with an embodiment, the control circuitry 116 in the training phase may be further configured to track electrical brain activity of the user 126 a in the plurality of sporting events by use of the set of internal response sensors 120. Typically, neurons in human brain communicate through electrical impulses. Such communication enables the brain to coordinate behaviour, sensation, and emotion. The electrical impulses signals are measurable using sensors attached to brain. There are usually spontaneous oscillations that defines the electrical activity of the human brain and the variation in these oscillations defines changes of state and type of brain activity. Many individuals for a same action or activity may have same, slightly different, or varied electrical brain activity. Further, same action under different circumstances in a sporting event may result in different electrical brain activity in same or different areas of brain. Thus, tracking electrical brain activity of individual user over a period of time provides a pattern of similarity and variations and when these similarity and variations are tagged with resultant performance, for example, good performance, average, or poor performance over a period of time, such data becomes powerful tool in electronic analysis of sports psychology just before a sporting event, during sporting event, and post specified time interval after completion of the sporting event.

In an example, wearable, whole-scalp electroencephalogram (EEG) and/or functional near-infrared spectroscopy (fNIRS) may be embedded in a headgear, such as a helmet worn by a player, for direct monitoring of brain activity during a sporting event or during training, exercise, and practice for a sporting event. A known technical problem with tracking electrical brain activity, for example, using EEG is that genuine cerebral data is often contaminated by artifacts of non-cerebral origin, for example, various body movement during exercise and when performing sports activities and/or due to physical exertion in a sporting event. The control circuitry 116 effectively handles such tracking of electrical brain activity by masking the effect of such artifacts, to obtain reliable tracked data. The control circuitry 116 is further configured to tag such electrical brain activity with stationery and motion parameters (e.g. “acquired when stationary” and “acquired when in motion”). Beneficially, this provides valuable information of potential artefacts signal patterns associated with wearable devices that are used to capture the electrical brain activity, such as EEG, thereby reduces the risk of misinterpretation during tracking of such electrical brain activity in a given sporting event. Such signal patterns may be removed (or masked or ignored) from the sensor data related to electrical brain activity. For example, comparison of amplitudes in alpha and beta band for various a time interval before, during and after specified time interval of a shot in a sporting event, and associated result of the shot (e.g. good, average, or bad performance) provides through understanding of signals that are associated with good performance, for example, 90% of time.

In accordance with an embodiment, the control circuitry 116 in the training phase may be further configured to track physiological changes induced in the body of the user 126 a in the plurality of sporting events by use of the set of internal response sensors 120. The physiological changes in the body of a user may refer to changes in activity in muscles or nerves, blood pressure, heart rate, breathing rate, body temperature, and/or pulse rate. For example, in aerobic training, weight and volume of a heart increases. In another example, myocardium muscle experience hypertrophy (an enlargement). Further, fiber composition in muscles also changes or certain fibers, such as fast-twitch fibers, are more used in quick and short body movements, such as performed in hockey. The capacity of the capacity of VO2 (volume of oxygen) also increases with sports endurance. VO2 refers to the maximum rate of oxygen consumption measured during incremental exercise or sporting activity. Moreover, hormonal, lipid, carbohydrates composition may also change over a period of time. Further, the physiological changes induced in the body may further include amount of lactate and glucose in the body. These variables when tracked in the plurality of sporting event for a same user, such as the user 126 a, may be analyzed to provide a detailed understanding of where the user 126 a needs to focus to improve sports performance.

In accordance with an embodiment, the control circuitry 116 may be configured to store tracking data obtained from the tracked locomotion, the tracked body movements, the tracked electrical brain activity, and the tracked physiological changes for the user 126 a in each sporting event of the plurality of sporting event. The control circuitry 116 may be configured to track and acquire a plurality of variables associated with tracked locomotion, the tracked body movements, the tracked electrical brain activity, and the tracked physiological changes in synchronization with each other. Alternatively stated, individual tracking may not provide reliable and meaningful data, but when tracked in association with other, the artefacts and noise related to different sensors of the set of internal sensors 120 and the set of external sensors 122 are minimized or almost nullified.

In accordance with an embodiment, the control circuitry 116 in the training phase may be further configured to assign a sports performance state to the user 126 a at completion of each sporting event of the plurality of sporting events based on a combination of sports statistics acquired from at least one specified online data source and at least one of a coach-feedback of the user 126 a or a self-feedback by the user 126 a. The electronic training system 104 a takes the advantage of an expertise of a coach and incorporates such feedback into the electronic training system 104 a for practical and usable output which is more relevant for the user 126 a undergoing the sports training as well as the coach providing the sports training to enhance sports performance. Typically, a sportsman is classified into a beginner stage, an intermediate stage, and a professional stage. Each stage may further have different sports performance state, which may be defined as level 1 to level 10, level 1 the lowest performance level of a given stage and the level 10, the highest level. When a sportsman achieves level 10, next stage is automatically assigned, and the counter is reset to level 1. Once the sportsman achieves the level 10 of professional stage, a new stage is created with a difficulty level higher than the previous stage, and the counter of level is reset to level 1. Thus, the sports performance state is a combination of a stage and a level assigned to that stage. The sports performance state not only employs user-feedback (such a coach feedback or a self-feedback of the user 126 a, or a combination of the coach feedback and the self-feedback), but also acquires sports statistics of the user 126 a from online information source, such as a social network, a sports website, and the like. The sports statistics may be used to determine whether the sports performance feedback from the coach and the self-feedback is not having any human biases, and also a comparative performance of the user 126 a in relation to other players of a given sporting event is also checked. Based on the combination of the sports statistics, the coach-feedback, and the self-feedback, a more accurate and unbiased sports performance state may be assigned in each sporting event of the plurality of sporting event by the control circuitry 116 in the training phase.

In accordance with an embodiment, the control circuitry 116 may be configured to store a learned sports performance dataset in the server arrangement 102 or a local storage system. The learned sports performance dataset may include a plurality of historical sports performance states and associated tracked data by the set of internal response sensors 120 and the set of external response sensors 122. The plurality of historical sports performance states corresponds to the assigned sports performance state to the user 126 a at completion of each sporting event of the plurality of sporting events. The tracked data for each sporting event is tagged with metadata that facilitates extraction of tracked data for a specific sporting event from the plurality of sporting events.

In accordance with an embodiment, the control circuitry 116 may be further configured to annotate tracked data in the sporting event as a set of period-of-relevance and a set of period-of-irrelevance based on a correlation in the tracked locomotion, the tracked body movements, the tracked electrical brain activity, and the tracked physiological changes for the user 126 a in each sporting event of the plurality of events. In an example, the set of period-of-relevance may be determined by segregation of the tracked data for a given sporting event into short action time intervals (i.e. a time interval that defines a specific shot or action in a sporting activity). In an example, the time interval may include an elapsed time period before a shot, during a shot, and a specified time period after the shot in a tennis sport. Such action time intervals may be then correlated with other tracked data related to the tracked electrical brain activity, and the tracked physiological changes for the user 126 a. The remaining data where no relevant action is detected from all the tracked body movements, the tracked electrical brain activity, and the tracked physiological changes may be ignored and tagged as the set of period-of-irrelevance. The annotated tracked data as the set of period-of-relevance for each sporting event along with the assigned sports performance state may be used as training dataset for the local-AI based system 124. The learned sports performance dataset further includes the learnings derived from such annotated tracked data as the set of period-of-relevance for each sporting event along with the assigned sports performance state.

In accordance with an embodiment, the plurality of electronic training system 104 may operate in a connected mode or a standalone mode. In the connected mode, each electronic training system 104 a, 104 b, . . . , 104 n, may be configured to communicate the annotated tracked data as the set of period-of-relevance for each sporting event along with the assigned sports performance state to the server arrangement. Thereafter, the server arrangement 102 may be configured to extract datapoints as training dataset from the annotated tracked data that corresponds to the set of period-of-relevance and convert the datapoints into an AI-readable format to feed into the main AI-based system 114. In the standalone mode, the extraction of datapoints as training dataset from the annotated tracked data that corresponds to the set of period-of-relevance and conversion of the datapoints into an AI-readable format occurs at corresponding electronic training system 104 a, 104 b, . . . , 104 n.

Like the training phase, the control circuitry 116 in the operational phase may be further configured to track locomotion and body movements of the user 126 a from the set of external response sensors 122 in a sporting event (i.e. a new sporting event). The control circuitry 116 may be further configured to track electrical brain activity and physiological changes in a body of the user 126 a from the set of internal response sensors 120 in the sporting event. The control circuitry 116 may be further configured to annotate tracked data in the sporting event as a set of period-of-relevance and a set of period-of-irrelevance based on a correlation in the tracked locomotion, the tracked body movements, the tracked electrical brain activity, and the tracked physiological changes for the user in the sporting event. The control circuitry 116 may be further configured to assign a first sports performance state to the user 126 a at completion of the sporting event based on a combination of a user feedback (e.g. a coach feedback or self-feedback of the user 126 a) and sports statistics acquired from at least one specified data source (e.g. an online data source).

The control circuitry 116 may be further configured to output a first integrated visual motion model on a display device based on annotated tracked data in the set of period-of-relevance. The integrated visual motion model comprises a first visual representation of the tracked locomotion and the body movements, a second visual representation of the tracked electrical brain activity, and a third visual representation of the tracked physiological changes in the body that are merged in the first integrated visual motion model and time-controlled at output such that the first sports performance state of the user 126 a for the sporting event is discernible by a viewer. In accordance with an embodiment, the first integrated visual motion model is a three-dimensional (3D) computer graphic model (hereinafter referred to as 3D model) of the user 126 a that reflects the external as well internal changes in a meaningful synchronization during the set of period-of-relevance in the sporting event. For example, in conventional systems when a player playing golf plays a stroke, the motion of arms and body posture may be captured by image-capture devices, and may be viewed later in slow-motion to manually evaluate sports performance with respect to result achieved for that stroke, a ball misses to be holed. However, in conventional systems, many other reasons and causes that lead to the result are usually ignored. In contrast to the conventional systems, the output of the first integrated visual motion model provides a synergistic view of changes in the tracked locomotion and the body movements, the tracked electrical brain activity, and the tracked physiological changes in the body when the player playing golf plays the stroke. In an example, the second visual representation of the tracked electrical brain activity may be visible within the 3D model of the user 126 a. similarly, the third visual representation of the tracked physiological changes in the body may be visible within the 3D model of the user 126 a. In other words, multiple 3D models (the first, second, and third visual representation) are merged with each other to reflect changes in a synergistic manner. An example of the first integrated visual motion model is shown and described in FIG. 3B.

In accordance with an embodiment, the control circuitry 116 in the operational phase may be further configured to output a second integrated visual motion model along the first integrated visual motion model as feedback. The second integrated visual motion model is outputted based on a comparison of the assigned first sports performance state with the stored learned sports performance dataset that comprises the plurality of historical sports performance states and associated tracked data. The second integrated visual motion model indicates a set of positive performance activities (e.g. good performances) and a set of negative performance activities (e.g. bad performances) in relation to the first sports performance state of the user 126 a for the sporting event.

In accordance with an embodiment, the user 126 a may want to set a goal to reach a target sports performance by constantly challenging self for improvement in sports performance. The electronic training system 104 a provides a mechanism by which a user, such as the user 126 a, is challenged to improve not only technical skills in sports, but also phycological and tactical training is imparted using various stimulus provided by the stimulus device 118. The control circuitry 116 may be further configured to receive an input via a user interface rendered on a display device communicatively coupled to the electronic training system 104 a. The input comprises a current sports performance state and a target sports performance state of the user 126 a. The input may include user formation pertaining to a current sports performance state and a target sports performance state that is intended to be achieved for the user 126 a. In an embodiment, other details, for example, physical characteristics of the user 126 a, a geography, a feedback from a dietician, a current training plan, may also be provided via the user interface 216 a.

In accordance with an embodiment, the control circuitry 116 may be further configured to retrieve at least one priori stimulus from a sports knowledge database based on the received input. In one example, the priori stimulus may correspond to a stimulus that is known based on existing knowledge in sports to influence one or more sports performance factors in the current sports performance state of the user 126 a. The control circuitry 116 may be further configured to determine a set of test stimuli specific for the user 126 a based on a combination of the current sports performance state, the target sports performance state, the retrieved at least one priori stimulus, and a trained Artificial Intelligence (AI) system, such as the local AI-based system 124 or the main AI-based system 114.

In accordance with an embodiment, the control circuitry 116 may be further configured to control the stimulus device 118 to provide the determined set of test stimuli to the user 126 a for a first test duration. The plurality of stimuli may include calibrated pressure, calibrated vibration input, calibrated electric input, calibrated magnetic input, hot and cold application, touch sense-based input, sound waves, and/or the like. The plurality of stimuli may further include presenting a VR-based digital environment. The VR-based digital environment may be a combination of audio effects and visual effects. The control circuitry 116 may be configured to control the stimulus device 118 for providing the plurality of stimuli on various body portions of the users 126 a. The local AI-based system 124 may provide, to the control circuitry 116, a first output that is indicative of one or more stimulus parameters and a first test duration for which the determined set of test stimuli may be applied to the user 126 a. Based on the first output, the control circuitry 116 may be configured to activate the stimulus device 118 for providing the determined set of test stimuli to the user 126 a for the first test duration. In accordance with an embodiment, the control circuitry 116 may be configured to activate a single stimulus sub-device or a set of stimulus sub-devices from the plurality of different stimulus sub-devices 106 at a given timepoint in the first test duration for providing the determined set of test stimuli to the user 126 a.

In accordance with an embodiment, the control circuitry 116 may be further configured to determine, based on the set of internal response sensors 120, a first set of responses within the body of the user 126 a from the provided set of test stimuli. The control circuitry 116 may be further configured to determine, based on the set of external response sensors 122, a second set of responses discernible on the body of the user 126 a from the provided set of test stimuli. As a result of the application of the determined set of test stimuli to the user 126 a for the first test duration, the first set of responses (i.e. internal responses) may be generated within the body of the user 126 a and the second set of responses (i.e. external responses) may be discernible from an external surface of the body of the user 126 a.

Each stimulus of the plurality of stimuli may generate a plurality of responses (for example, one or more internal responses and one or more external responses) in the body of the user 126 a. Examples of the one or more internal responses may include, but are not limited to, nerve conduction, neuron firing, activity in muscles or nerves, activity in brain, alteration in blood pressure, and/or alteration in pulse rate. Examples of the one or more external responses that are discernible from external surface of the body may include, but are not limited to, locomotion and body movements, change in gestures, a body posture, a change in skin colour, and/or a voice feedback. The control circuitry 116 may be further configured to instruct the set of external response sensors 122 and the set of internal response sensors 120 to sense and measure levels of the one or more external responses and one or more internal responses generated in the body portions of the user 126 a due to the application of the plurality of stimuli to the user 126 a. The control circuitry 116 may be further configured to process sensor data acquired by the set of internal response sensors 120 and the set of external response sensors 122 pertaining to the first set of responses and the second set of responses, respectively.

In accordance with an embodiment, the control circuitry 116 may be further configured to detect which muscle in the body, which area in brain, or which nerve is responding each provided stimulus of the set of test stimuli. In other words, if there are any changes in the electrical brain activity and any physiological change within the body of the user 126 a is ascertained based on processing of tracked data. The control circuitry 116 may be further configured to quantify the level of response measured by the set of internal response sensors 120.

In accordance with an embodiment, the control circuitry 116 may be further configured to establish an associative relationship between each stimulus-response pair from the first set of responses and the second set of responses using the local AI-based system 124. In some embodiment, for example, in the connected mode, the plurality of electronic training systems 104 may be configured to communicate the determined plurality of stimulus-response pairs to the server arrangement 102. Each stimulus-response pair is indicative of a type of stimulus that was applied and a level of each response that was generated based on the applied stimulus. The plurality of electronic training systems 104 may be further configured to communicate additional details (such as user information) pertaining to the users 126 a to 126 n to the server arrangement 102. The main AI-based system 114 in the connected mode (or the local AI-based system 124 in the standalone mode) may be configured to establish an associative relationship between each stimulus-response pair in the plurality of stimulus-response pairs to generate stimulus-response (SR) pair dataset (as shown in FIG. 2 ). In one exemplary scenario, the SR pair dataset may be a tabular database having a plurality of rows and columns. Each row may be associated with a single stimulus and may indicate the level of responses that were generated based on the corresponding single stimulus. The main AI-based system 114 in the connected mode (or the local AI-based system 124 in the standalone mode) may be configured to store the generated SR pair dataset in a memory (such as storage systems).

The control circuitry 116 may be further configured to determine a plurality of causes of similarity and variability based on the established associative relationship. The main AI-based system 114 in the connected mode (or the local AI-based system 124 in the standalone mode) may be configured to determine a plurality of causes of similarity and variability in the plurality of responses based on the established associative relationship between each of the plurality of stimulus-response pairs, user information, and the available sports knowledge. Examples of the plurality of causes of similarity and variability determined by the main AI-based system 114 in the connected mode (or the local AI-based system 124 in the standalone mode) may include, but are not limited to, age groups, sports endurance under same conditions, nutrition intake, genomic, body weight, body mass index (BMI), ailment, or the like. The main AI-based system 114 in the connected mode (or the local AI-based system 124 in the standalone mode) may be further configured to segregate the generated SR pair dataset into a plurality of training categories, for example a first training category, a second training category, and a third training category. The first training category may include a first set of stimulus-response pairs that is generally suitable for a group of people, such as all team members of a team. Similarly, the second training category may include a second set of stimulus-response pairs that is suitable for one or more specific traits, for example, similar age group, similar sports performance issues, similar sports, and/or the like. Likewise, the third training category may include a third set of stimulus-response pairs that is suitable for a specific user, i.e. segregated into subsets of stimulus-response pairs each personalized for a specific user. In accordance with an embodiment, the main AI-based system 114 may be configured to utilize supervised or unsupervised learning to find relationships among the plurality of stimulus-response pairs included in the SR pair dataset for segregation of the SR pair dataset. Thus, all the stimulus-response pairs included in the SR pair dataset may be categorized and then sub-categorized and a learning may be derived. Based on the segregated SR pair dataset, the main AI-based system 114 is trained to generate a trained neural network model (i.e., the trained main AI-based system 114).

The learnings of the trained main AI-based system 114 may be used to update the local AI-based system 124, by a transfer-learning operation from the trained main AI-based system 114 to the local AI-based system 124. For example, the segregated SR pair dataset may be communicated from the server arrangement 102 to each of the plurality of electronic training systems 104 by the transfer-learning operation. In some embodiments, the trained main AI-based system 114 may be used for deployment into a new electronic training system 104 a. The main AI-based system 114 may function as a main AI and the local AI-based system 124 may function as a local AI, which may be updated as and when required by the main AI-based system 114. The local AI-based system 124 may be computationally lighter (e.g. having a smaller number of hidden layers as compared to the main AI-based system 114).

In accordance with an embodiment, the control circuitry 116 is further configured to calibrate a set of stimulus parameters for the stimulus device 118 based on a combination of the determined first set of responses, the second set of responses, the current sports performance state, the target sports performance state, and the trained artificial intelligence-based system. The stimulus device 118 is re-configured with the calibrated set of stimulus parameters to apply a new stimulus to the user 126 a for a second duration. The use of the new stimulus shifts the current sports performance state towards the target sports performance state. The local AI-based system 124 may be configured to provide a second output to the control circuitry 116 based on the determination of the new stimulus. The second output may indicate the set of stimulus parameters, a second duration for which the new stimulus is to be applied to the target user 130, and one or more targeted body portions where the new stimulus is to be applied. The second duration for which the new stimulus is to be applied to the target user 130 may be greater than the first test duration. In an embodiment, the new stimulus may not be available during the training phase. In another embodiment, the new stimulus having the set of stimulus parameters is an existing stimulus that was available during the training phase. The trained electronic training system 104 a may be utilized for improving a stamina and sports performance of a sportsman by the new stimulus. The trained electronic training system 104 a may detect the current sports performance state of a sportsman, and continuously challenge his endurance, fitness, engagement, sports move, and the like, to improve sports performance.

In accordance with an embodiment, the stimulus device 118 may be configured to output a first digital environment around the user 126 a. The first digital environment may be a human sense stimulating mixed reality environment that induces a specific stimulus to the user 126 a to increase sports performance from the first spots performance state to a second sports performance state of the user 126 a. In other words, the first digital environment may be electronically generated mixed reality environment that activates certain areas of brain or de-novo facilitate generation of well-being chemicals, such as endorphins. The mixed reality environment may be a combination of a virtual environment (e.g. a virtual reality environment) and tangible elements, for example, that may provide a stimulus to a human body or a portion of a human body. In one example, the stimulus device 118 may be used to provide certain tangible stimulus (e.g. heat, smell, pressure, cold, sound, a digital visualization) that acts on one or more senses of the plurality of human senses (5 senses) as a part of the first digital environment, such as audio-visual environment created by the stimulus device 118. In another example, the stimulus device 118 may be configured to generate magnetic field at different frequency as a part of the first digital environment. In an example, a sub-device of the stimulus device 118, such as a VR scene projecting sub-device, may be used to project audio-visual scenes around a user to challenge the user 126 a from the current sports performance state to the target sports performance state. The audio-visual scenes projected by the VR scene projecting sub-device 106 h may stimulate hearing and visual senses of the user 126 a.

In accordance with an embodiment, the control circuitry 116 may be further configured to determine a response to the specific stimulus provided by the output of the first digital environment around the user 126 a. Thus, the local AI-based system 124 may be further tuned to find relationships as to how an individual is responding to a provided stimulus (or the outputted digital environment). All these information pieces (i.e. relationships) may be grouped and then sub-grouped and a learning may be derived. For example, it may be found if there exists a correlation, or no correlation, or less correlation among the analysed information. Further, the process of tagging and elimination for each data point may be executed to identify correct correlation, inferences, and response(s) to provided stimulus, based on continuous training. Thus, a trained model (i.e. a trained local AI-based system 124) may be obtained.

In accordance with an embodiment, the stimulus device 118 is further configured to output a second digital environment around the user 126 a with a difficulty level that is greater than the difficulty level of the first digital environment. The second digital environment is a human sense stimulating mixed reality environment that induces a new stimulus to the user 126 a to increase sports performance further from the second sports performance state to a new sports performance state of the user 126 a. The second digital environment may be similar to that of the first digital environment but may differ in that the second digital environment provides more challenges to the user 126 a to solve. For example, the user 126 a may want to set a goal to reach a target sports performance by constantly challenging self for improvement in sports performance. The electronic training system 104 a provides a mechanism by which a user, such as the user 126 a, is challenged to improve not only technical skills in sports, but also phycological and tactical training is imparted using various stimulus provided by the stimulus device 118. The trained electronic training system 104 a may detect the current sports performance state of a sportsman, and continuously challenge his endurance, fitness, engagement, sports move, and the like, to improve sports performance.

In accordance with an embodiment, the control circuitry 116 is further configured to generate a stimulation instruction pack specific for the user 126 a based on an output from a trained artificial intelligence-based system. The control circuitry is further configured to activate a single stimulus sub-device or a set of stimulus sub-devices from the plurality of different stimulus sub-devices 106 at a given timepoint in a first duration in accordance with the generated stimulation instructions pack. The stimulation instruction pack may include a type of control signal for the plurality of different stimulus sub-devices 106, a time schedule, an intensity of output, and a set of sense identifiers. The time schedule may define a specific activation time and a specific duration to generate the new stimulus in the second duration by using one or more stimulus sub-devices of the plurality of different stimulus sub-devices 106 under the control of the stimulus device 118. Each sense identifier of the set of sense identifiers may indicate a unique specific sense stimulating item to be selected for output in accordance with the time schedule. For example, a first sense identifier may indicate a specific smell for output. In such a case, the intensity of output defines what amount of liquid or gas to be sprayed and in which direction. The stimulus device 118 may be configured to select a unique specific sense stimulating item (for example, an odor generating item, a visual effects item, an audio effects item, and a touch-sense based item) for generating a single or multiple sense stimulating output/s to stimulate a specific sense/s of a plurality of human senses based on the type of control signal included in the stimulation instruction pack. Thus, based on the stimulation instruction pack, the stimulus device 118 is re-configured with the calibrated set of stimulus parameters and the new stimulus is applied to at least targeted body portions of the user 126 a to enhance the current sports performance.

In accordance with an embodiment, the local AI-based system 124 and the control circuitry 116 may continue to improve and personalize the stimulus applied to the user 126 a based the internal responses and the external responses exhibited by the user 126 a for achieving the target sports performance state. In accordance with an embodiment, the electronic training system 104 a may operate in the connected mode. While in the online mode, the electronic training system 104 a may operate under the control of the server arrangement 102. Thus, based on the setting of the connected mode at the electronic training system 104 a, the main AI-based system 114 may be configured to execute the same operations as executed by the local AI-based system 124 in the standalone mode.

In accordance with an embodiment, the control circuitry 116 may be further configured to determine whether an alteration is required in a training plan for the current sports performance state of the user 126 a, based on the application of the new stimulus to the user 126 a for the second duration and a shift in the at least one sports performance indicator of the user 126 a from the current sports performance state towards the target sports performance state. The control circuitry 116 may be further configured to determine a new training plan that is different from the training plan for the current sports performance state of the user 126 a based on the determination that the alteration is required. The control circuitry 116 may be further configured to communicate a training change recommendation for the user 126 a to a prespecified user device 108 of a coach of the user 126 a. The training change recommendation comprises the new training plan for the target sports performance state and a plurality of sports performance indicators that indicates the shift from the current sports performance towards the target sports performance state for the user 126 a.

In an exemplary implementation, the control circuitry 116 may be configured to retrieve known sports performance information of a plurality of users (e.g. User 1 and user 2). The known sports performance information may be retrieved from a sports knowledge database stored locally in the electronic training system 104 a, from the server arrangement 102, or directly parsed from Internet-based sources. The control circuitry 116 may be further configured to create a VR environment game based on the retrieved known sports performance information of the plurality of users. The VR environment game may then be used to train a user to learn new skills.

In another exemplary implementation, the control circuitry 116 may be configured to retrieve sports performance information of different players (e.g. players from opposite teams). The control circuitry 116 may be further configured to utilize the retrieved sports performance information to create a group-based VR which induces challenges for a user (or opponents) who uses the electronic training system 104 a to train the user (or opponents). Further, in order to train a team, the control circuitry 116 may be configured to combine the sports performance information of selected or all players of the team to create a group-based VR environment for training. In an example, the control circuitry 116 may be configured to create a new VR environment by feeding information for a user who is part of training therapy into the VR environment. For example, if a first user have problems with his/her child, parent, or a second user known to the first user, the information related to the child, parent, or the second user may be fed into the VR environment to create the training therapy for the first user. In addition to improvement in sports performance, such training therapy may also find application in physical therapy, or other surgical or medical training therapies. Moreover, learned information related to sports performance learned from different players by the electronic training system 104 a may be fed into the VR environment so that all the knowledge (i.e. learnings in terms of technical skills, phycological and tactical skills) may be passed to a user who may be under training. Sports performance for celebrities and famous players (e.g. Messi) is available and may be incorporated into the VR environment to create a game or a VR-based gaming environment, which in turn may be used to train a user, team members of a team, or train opponents of a sport or game.

With reference to FIG. 3A, there is shown a graphical representation 300A of an exemplary tracked data for an exemplary time interval for annotation of the tracked data in a sporting event for the purpose of electronic evaluation of sports performance of a user (such as the user 126 a of FIG. 1 ). In the graphical representation 300A, there is further shown a first signal 302A to denote tracked body movements, a second signal 302B to denote tracked electrical brain activity, and a third signal 302C to denote tracked physiological changes for the user 126 a (not shown) in a given sporting event.

In accordance with an embodiment, the control circuitry 116 may be configured to annotate tracked data in the sporting event as a set of period-of-relevance, such as a first period-of-relevance 306A, a second period-of-relevance 306B, and a third period-of-relevance 306C, and a set of period-of-irrelevance, such as a first period-of-irrelevance 304A, a second period-of-irrelevance 304B, and a third period-of-irrelevance 304C. The tracked data is segregated and annotated into periods-of-relevance and irrelevance based on a correlation in the tracked body movements, the tracked electrical brain activity, and the tracked physiological changes for the user 126 a in the given sporting event.

In accordance with an embodiment, the control circuitry 116 may be configured to output the first integrated visual motion model 300B on the display 216 based on annotated tracked data in the set of period-of-relevance. The integrated visual motion model 300B comprises a first visual representation 308 of the tracked locomotion and the body movements, a second visual representation 310 of the tracked electrical brain activity, and a third visual representation 312 of the tracked physiological changes in the body that are merged in the first integrated visual motion model 300B and time-controlled at output such that the first sports performance state of the user 126 a for the given sporting event is discernible by a viewer.

In accordance with an embodiment, the first integrated visual motion model 300B is a three-dimensional (3D) computer graphic model (hereinafter referred to as 3D model) of the user 126 a that reflects the external as well internal changes in a meaningful synchronization during the set of period-of-relevance in the given sporting event. The first integrated visual motion model 300B may be a visual scene that depicts metadata and meaningful information that indicates various reasons and causes that led to the first sports performance state of the user 126 a assigned by the control circuitry 116.

For example, when a movement is performed by the user 126 a, for example, kicking a soccer ball, not only the motion of kick, is visible in the first visual representation 308, but also some portion of the first visual representation is turned transparent so that internal changes, such as blood flow, VO2, heart rate, lactic acid formation in muscle is visible via the second layer, such as the second visual representation 310 as well as electrical brain activity or neuron firing via the third visual representation 312 of the user 126 a is visible too. Further, meaning of such visible data in terms of what is considered a good performance and where there is scope of improvement is also determined and rendered beside the first integrated visual motion model 300B based on the LSP dataset 222. A reference to previous performance of the user 126 a in a previous sporting event, in which the user 126 a was comparatively better or poor in terms of sports performance state for the similar type of game situation (e.g. similar motion of limbs during a kick of the soccer ball) is also automatically retrieved and presented on the user interface 216 a of the display 216. This provides a holistic and enhanced understanding of the sports performance state for each relevant action in the set of period-of-relevance in the given sporting event.

FIG. 3C illustrates an exemplary scenario for implementation of the electronic training system of FIG. 1 , in accordance with an exemplary embodiment of the disclosure.

With reference to FIG. 3C, there is shown an exemplary scenario 300C that depicts a user interface 314 with a first integrated visual motion model 316 along with a second integrated visual motion model 316 rendered side-by-side for providing feedback to the user 126 a to improve sports performance. The first integrated visual motion model 316 may correspond to the first integrated visual motion model 300B of FIG. 3B. The user interface 314 may correspond to the user interface 216 a.

In accordance with an embodiment, the control circuitry 116 in the operational phase may be further configured to output the second integrated visual motion model 316 along the first integrated visual motion model 314 as feedback via the user interface 314. The second integrated visual motion model 316 is outputted based on a comparison of the assigned first sports performance state with the stored learned sports performance dataset 222 (or LSP dataset 210) that comprises the plurality of historical sports performance states and associated tracked data. The second integrated visual motion model 316 indicates a set of positive performance activities and a set of negative performance activities in a given sporting event. In this case, the second integrated visual motion model 316 is retrieved from the LSP dataset 222 or 210 based on a similar action performed to achieve a similar result, such as a goal in a soccer match from a given positions of players in a field. In one example, the second integrated visual motion model 316 may be one of the sports' performance of the same user 126 a who may have played better in one of previous sporting events as compared to current sporting event. Thus, a side-by-side visual comparison of the same user 126 a acts as an evidence and a practical feedback what works well (i.e. a positive performance activity) and what does not work well (i.e. a negative performance activity) under a similar situation in a sporting event for the user 126 a.
